Rh to have had a warm affection for his countrymen, it was as human beings brought into contact with him, and not as members of a political body, that he preferred to regard them. He never entered public life. His kindliness extended even to his slaves, one of whom, named Mouse, was a brother in philosophy.

Epicurus died of stone in 270 He left his property, consisting of the garden ( ), a house in Melite (the south-west quarter of Athens), and apparently some funds besides, to two trustees on behalf of his society, and for the special interest of some youthful members. The garden was set apart for the use of the school; the house became the house of Hermarchus and his fellow-philosophers during his lifetime. The surplus proceeds of the property were further to be applied to maintain a yearly offering in commemoration of his departed father, mother and brothers, to pay the expenses incurred in celebrating his own birthday every year on the 7th of the month Gamelion, and for a social gathering of the sect on the 20th of every month in honour of himself and Metrodorus. Besides similar tributes in honour of his brothers and Polyaenus, he directed the trustees to be guardians of the son of Polyaenus and the son of Metrodorus; whilst the daughter of the last mentioned was to be married by the guardians to some member of the society who should be approved of by Hermarchus. His four slaves, three men and one woman, were left their freedom. His books passed to Hermarchus.

Philosophy.—The Epicurean philosophy is traditionally divided into the three branches of logic, physics and ethics. It is, however, only as a basis of facts and principles for his theory of life that logical and physical inquiries find a place at all. Epicurus himself had not apparently shared in any large or liberal culture, and his influence was certainly thrown on the side of those who depreciated purely scientific pursuits as one-sided and misleading. “Steer clear of all culture” was his advice to a young disciple. In this aversion to a purely or mainly intellectual training may be traced a recoil from the systematic metaphysics of Plato and Aristotle, whose tendency was to subordinate the practical man to the philosopher. Ethics had been based upon logic and metaphysics. But experience showed that systematic knowledge of truth is not synonymous with right action. Hence, in the second place, Plato and Aristotle had assumed a perfect state with laws to guide the individual aright. It was thus comparatively easy to show how the individual could learn to apprehend and embody the moral law in his own conduct. But experience had in the time of Epicurus shown the temporary and artificial character of the civic form of social life. It was necessary, therefore, for Epicurus to go back to nature to find a more enduring and a wider foundation for ethical doctrine, to go back from words to realities, to give up reasonings and get at feelings, to test conceptions and arguments by a final reference to the only touchstone of truth—to sensation. There, and there only, one seems to find a common and a satisfactory ground, supposing always that all men’s feelings give the same answer. Logic must go, but so also must the state, as a specially-privileged and eternal order of things, as anything more than a contrivance serving certain purposes of general utility.

To the Epicureans the elaborate logic of the Stoics was a superfluity. In place of logic we find canonic, the theory of the three tests of truth and reality. (1) The only ultimate canon of reality is sensation; whatever we feel, whatever we perceive by any sense, that we know on the most certain evidence we can have to be real, and in proportion as our feeling is clear, distinct and vivid, in that proportion are we sure of the reality of its object. But in what that vividness ( ) consists is a question which Epicurus does not raise, and which he would no doubt have deemed superfluous quibbling over a matter sufficiently settled by common sense. (2) Besides our sensations, we learn truth and reality by our preconceptions or ideas ( ). These are the fainter images produced by repeated sensations, the “ideas” resulting from previous “impressions”—sensations at second-hand as it were, which are stored up in memory, and which a general name serves to recall. These bear witness to reality, not because we feel anything now, but because we felt it once; they are sensations registered in language, and again, if need be, translatable into immediate sensations or groups of sensation. (3) Lastly, reality is vouched for by the imaginative apprehensions of the mind ( ), immediate feelings of which the mind is conscious as produced by some action of its own. This last canon, however, was of dubious validity. Epicureanism generally was content to affirm that whatever we effectively feel in consciousness is real; in which sense they allow reality to the fancies of the insane, the dreams of a sleeper, and those feelings by which we imagine the existence of beings of perfect blessedness and endless life. Similarly, just because fear, hope and remembrance add to the intensity of consciousness, the Epicurean can hold that bodily pain and pleasure is a less durable and important thing than pain and pleasure of mind. Whatever we feel to affect us does affect us, and is therefore real. Error can arise only because we mix up our opinions and suppositions with what we actually feel. The Epicurean canon is a rejection of logic; it sticks fast to the one point that “sensation is sensation,” and there is no more to be made of it. Sensation, it says, is unreasoning ( ); it must be accepted, and not criticized. Reasoning can come in only to put sensations together, and to point out how they severally contribute to human welfare; it does not make them, and cannot alter them.

Physics.—In the Epicurean physics there are two parts—a general metaphysic and psychology, and a special explanation of particular phenomena of nature. The method of Epicurus is the argument of analogy. It is an attempt to make the phenomena of nature intelligible to us by regarding them as instances on a grand scale of that with which we are already familiar on a small scale. This is what Epicurus calls explaining what we do not see by what we do see.

In physics Epicurus founded upon Democritus, and his chief object was to abolish the dualism between mind and matter which is so essential a point in the systems of Plato and Aristotle. All that exists, says Epicurus, is corporeal ( ); the intangible is non-existent, or empty space. If a thing exists it must be felt, and to be felt it must exert resistance. But not all things are intangible which our senses are not subtle enough to detect. We must indeed accept our feelings; but we must also believe much which is not directly testified by sensation, if only it serves to explain phenomena and does not contravene our sensations. The fundamental postulates of Epicureanism are atoms and the void ( ). Space is infinite, and there is an illimitable multitude of indestructible, indivisible and absolutely compact atoms in perpetual motion in this illimitable space. These atoms, differing only in size, figure and weight, are perpetually moving with equal velocities, but at a rate far surpassing our conceptions; as they move, they are for ever giving rise to new worlds; and these worlds are perpetually tending towards dissolution, and towards a fresh series of creations. This universe of ours is only one section out of the innumerable worlds in infinite space; other worlds may present systems very different from that of our own. The soul of man is only a finer species of body, spread throughout the whole aggregation which we term his bodily frame. Like a warm breath, it pervades the human structure and works with it; nor could it act as it does in perception unless it were corporeal. The various processes of sense, notably vision, are explained on the principles of materialism. From the surfaces of all objects there are continually flowing thin filmy images exactly copying the solid body whence they originate; and these images by direct impact on the organism produce (we need not care to ask how) the phenomena of vision. Epicurus in this way explains vision by substituting for the apparent action of a body at a distance a direct contact of image and organ. But without following the explanation into the details in which it revels, it may be enough to say that the whole hypothesis is but an attempt to exclude the occult conception of action at a distance, and substitute a familiar phenomenon.

The Gods.—This aspect of the Epicurean physics becomes clearer when we look at his mode of rendering particular phenomena intelligible. His purpose is to eliminate the common idea of
